[jira] [Updated] (SOLR-10376) Implement trigger for nodeAdded event

["Shalin Shekhar Mangar (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/SOLR-10376?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Shalin Shekhar Mangar updated SOLR-10376:
-----------------------------------------
    Attachment: SOLR-10376.patch

Here's a first cut at the implementation:
* Adds a TriggerThread that runs on the overseer and reads/updates the active triggers from ZooKeeper and hands them over to ManagedTriggers
* ManagedTriggers is responsible for scheduling and shutting down all triggers as well as handling trigger fires (this is still a WIP)
* NodeAddedTrigger is the class which actually handles the trigger by looking at the live nodes in cluster state
* NodeAddedTriggerTest tests the class -- more to do there.

More javadocs and tests to come in later patches.

> This issue is about implementing support for the nodeAdded event type. Whenever a node is added, all triggers for this event type should be fired.
